Nebuchadnezzar and those 80 years

James Ussher's chronology of 1650 and later chronologies have been used extensively in many editions of the King James Bible. They show the fall of Jerusalem as occurring around 586 BC, and followed Ptolemy's secular Canon of Kings (160 AD) - a list which excluded Darius the Mede.

The early church (and Jewish chronology) were very conscious of Daniel's 69 sevens prophecy that after 70 years of exile in Babylon, which had begun during the 1st year of Nebuchadnezzar Jeremiah 25:1-11, Daniel 1:1 the Jews were permitted to return to Jerusalem. There then followed "7 sevens" - of rebuilding the city and the walls - followed by "62 sevens" and then the Messiah would be cut off. Therefore, 70 years + 69 times 7 years meant there must have been 553 years prior to March 31 AD click here when the crucifixion occurred which takes us back to 523 BC (there is no year zero). Thus the 1st year of Nebuchadnezzar's reign involved coming to Jerusalem in 524 BC then taking Daniel and the others away perhaps around March 523 BC. Although the year is mentioned, the day and month is not. The destruction of the city occurred in his 19th year, in the month of July/August 506 BC rather than Ptolemy's account of 586 BC.

This introduced an 80 (or so) year discrepancy back to the foundation of the temple, which Ussher recorded as occurring in 1012 BC (instead of 931 BC). However, his use of that year being the "480th year" since the Exodus fails to account for 94 "enslaved" / uncounted years during the period of the Judges, as seen in Paul's account in the Book of Acts click here for these years. So it introduced a nett discrepancy of 14 years (or so) — the Exodus was recorded by him as occurring about 1491 BC (rather than 1505 BC) and Adam created in Oct 4004 BC (rather than Sep-Oct 4019 BC).
